Here are the links to a couple more speed painter entertainers. Why bother taking a look? Because adding a bit of showmanship to your chalk presentations is no sin and watching these guys may inspire you to kick it up a notch.
Rock Demarco markets himself as the World's Fastest Painter using a stage persona similar to Criss Angel...on steroids - kind of a punk rocker, goth, Freddie Kruger hybrid - tell me his "painting glove" doesn't remind you of the Nightmare on Elm Street villian.http://www.rockdemarco.com/
D. Westry is "The Man With the Hand - The Speed Art Man" This guy gives off an urban, hip hop kind of vibe. Also uses the rotating easel board.http://speedartman.com/Speedartman-v6_website/index.html
Michael Israel is, well, a cross between a classic 70s rock star, Fabio and Jackson Pollock. He has been described as Cirque du Soleil meets Picasso. His promo reel makes it look as though he uses a trampoline to get such awesome "air time" - whew!http://www.michaelisrael.com/
Study these guys - don't imitate but realize that a tasteful use of high energy passion will make your presentation better for the audience.
